The electrical safety of coal mining enterprises is directly related to the continuity of production. The electrical scenarios for underground mining operations are extremely special: high-power equipment is concentrated, power lines are widely distributed, and the environment is harsh with humidity (relative humidity often exceeds 90%), high dust, and the presence of flammable and explosive gases such as gas. Once an electrical failure occurs, it may not only cause safety accidents such as fire and leakage, threatening personnel's life safety, but also lead to production interruption and significant economic losses.

core pain point

Difficulty in adapting to underground environments: Traditional electrical monitoring equipment lacks explosion-proof qualifications, and its use in flammable and explosive environments containing gas can easily lead to safety accidents; The lines are often buried underground or laid along tunnels, with strong hidden dangers such as insulation damage and water immersion, making it difficult for manual inspections to fully cover them.

Large fluctuations in equipment load: Core equipment such as coal mining machines and scraper conveyors start and stop frequently, with large instantaneous current surges, which can easily cause line overload; Unauthorized access to high-power equipment such as temporary welding machines is difficult to detect and may cause overheating and burning of the circuit.

High risk of fault disposal: The underground fault points are scattered, and manual troubleshooting requires carrying equipment down the well, usually taking 1-2 hours, which can easily delay the disposal time; Leakage and other faults may cause electric shock to personnel, and even trigger gas explosions, posing great safety risks to operation and maintenance personnel.

In response to the issue of electricity consumption in coal mine safety production, Li'an Technology relies on "Dianyi Cloud" and has developed the "Coal Mine Smart Electricity Safety Monitoring System" based on AI artificial intelligence, big data, and cloud computing technology. Based on the special requirements of the underground environment, we aim to create an integrated smart and secure electricity solution that combines explosion-proof sensing terminals, multi network transmission, and cloud based intelligent control. This solution will accurately cover all scenarios of electricity demand, achieving a safety management upgrade from "passive emergency" to "active prevention".

　　

The A60 power monitoring terminal is used to monitor the current, voltage, electrical degree, leakage, and temperature of distribution lines, and promptly detect electrical faults such as leakage, temperature exceeding limits, overload, and overvoltage in electrical lines or equipment. According to the on-site situation, the A50 power monitoring detector can be selected and applied to occasions with phase voltage of 380V and above (common in industrial enterprises), monitoring the voltage, current, power, and energy measurement of various power equipment (motors, intermediate frequency furnaces, frequency converters), transformers.

Multi terminal real-time monitoring: supports web, mobile app, and underground large screen multi terminal access, annotates all monitoring points through GIS maps, intuitively displays equipment status, parameter curves, and hidden danger information, and facilitates dispatchers to grasp the real-time power consumption situation of the entire area;

Intelligent alarm linkage: hierarchical push of alarm information (computer web, mobile APP, SMS, phone, etc.), automatic linkage to cut off faulty power supply and start ventilation equipment in emergency situations, quickly reducing risks;

Data assisted decision-making: stores historical electricity consumption and fault data, supports multi-dimensional retrieval, automatically generates electricity consumption reports and fault analysis reports, and provides data support for equipment maintenance plan formulation;

Full traceability: Automatically retain equipment operation logs, alarm handling records, and operation records to form a complete electronic file that meets the traceability requirements of safety inspections.

This solution is not a simple combination of "equipment+platform", but a customized solution that deeply fits the characteristics of the coal mining industry. By adapting explosion-proof terminals to the special underground environment, ensuring smooth data transmission through multiple networks, and implementing intelligent control through cloud platforms, the pain points of difficult environmental adaptation, late detection of hidden dangers, and slow fault disposal in traditional electricity management have been completely solved. At the same time, it fully meets the strict requirements of coal mine safety production and builds a solid defense line for underground electricity safety.
